Tianshui Automatic Mobile Toilet

The Tianshui automatic mobile toilet is a representative upgraded urban public service facility that integrates mobility with multiple real-time management and environmental control technologies, featuring flexible deployment and high-level self-control.

I. Automation System and Intelligent Control
The Tianshui automatic mobile toilet incorporates an integrated automation system inside, utilizing various sensor modules for environmental monitoring and usage status identification. Environmental sensors can continuously monitor the concentrations of odor gases such as ammonia and hydrogen sulfide, while induction devices count the foot traffic and identify the occupancy status of toilet stalls. After all data is transmitted to the local control unit, the system automatically triggers processing mechanisms based on preset thresholds or usage frequencies: when the odor concentration exceeds the standard, it activates a powerful ventilation system or sprays environmentally friendly deodorizers; when determining cleaning needs based on usage frequency, it prompts for in-depth maintenance. This process significantly reduces manual intervention and ensures service quality during unattended periods.

II. Self-Sufficiency in Energy and Water Resources
The facility employs independent energy and treatment modules to ensure sustainable operation. In terms of energy, it is equipped with solar photovoltaic panels and energy storage battery packs to meet the low-power requirements of lighting, sensing, and control systems, reducing reliance on the external power grid. For water resource treatment, it relies on recirculating water technology or biodegradation technology: the recirculating water system reuses flushing water through multi-stage purification, reducing freshwater consumption; the biodegradation technology utilizes microorganisms to decompose excreta, further reducing water resource demand and sewage discharge loads. These designs make it suitable for scenarios without municipal water supply or sewage pipelines.

III. Smart Services and Operational Optimization
The external electronic display terminal is an important manifestation of its 'smart' features, allowing users to obtain real-time information on toilet stall occupancy, internal temperature and humidity, and air quality, shortening waiting times and enhancing the user experience. All operational data is securely stored and analyzed locally, generating facility health reports and predicting the replacement cycles of consumables (such as deodorizers and purification filters) to enable preventive maintenance. This data-driven operational and maintenance model reduces the risk of sudden failures, extends the service life of the facility, and significantly improves overall efficiency.
